+changes in sbcl-1.0.1 relative to sbcl-1.0:
+ * improvement: sb-sprof traces call stacks to an arbitrary depth on
+ x86/x86-64, rather than the previous fixed depth of 8

+ * bug fix: non-required arguments were not passed correctly when a method
+ defined using DEFMETHOD was called from a mop-generated method using
+ CALL-NEXT-METHOD (reported by Pascal Costanza)
+ * bug fix: recursion is now permitted in accessors through
+ SLOT-UNBOUND. (reported by Pascal Costanza)
+ * bug fix: an error was signaled at startup if the HOME environment
+ variable was defined, but had an empty value (reported by Peter Van Eynde)
+ * bug fix: non ordinary lambda-list keyword in ordinary lambda lists
+ signal a PROGRAM-ERROR, not a BUG.
+ * bug fix: SB-POSIX:READDIR works when built with large file support.

+ are significantly faster on arrays whose element types have been
+ declared.
+
+changes in sbcl-1.0 relative to sbcl-0.9.18:
+ * improvement: experimental support for threading on FreeBSD/x86.
+ (thanks to NIIMI Satoshi)
+ * improvement: runtime option --dynamic-space-size can be used
+ to set the size of the dynamic space reserved on startup.
+ * improvement: floating point modes in effect are now saved in
+ core, and restored on startup.
+ * improvement: GET-INTERNAL-REAL-TIME now reports the time since
+ startup, not time since first call to GET-INTERNAL-REAL-TIME.
+ * improvement: SAVE-LISP-AND-DIE explicitly checks that multiple
+ threads are not running after *SAVE-HOOKS* have run.
+ * improvement: writes to CLOS instance slots are type-checked in code
+ compiled with (SAFETY 3)

+ Joshua Ross)
+ * bug fix: compiler bug triggered by a (non-standard) VALUES
+ declaration in a LET* was fixed. (reported by Kaersten Poeck)
+ * bug fix: file compiler no longer confuses validated and already
+ dumped structurres. (reported by Kaersten Poeck)
+ * bug fix: ADJUST-ARRAY :FILL-POINTER T on an array without a

+ Lars Brinkhoff)
+ * bug fix: disassemly of funcallable instances works.
+ * bug fix: single stepping on PPC.
+ * bug fix: fix thread-safety problems in the type system (generally
+ manifesting as nonsensical errors like "STRING is a bad type specifier
+ for sequences" or "The value 1 is not of type FIXNUM")
+ * bug fix: version components are handled correctly in TRANSLATE-PATHNAME
+ (reported by Josip Gracin)

+
+changes in sbcl-0.9.18 (1.0.beta?) relative to sbcl-0.9.17:
+ * enhancement: SB-POSIX now supports cfsetispeed(3), cfsetospeed(3),
+ cfgetispeed(3), cfgetospeed(3), and related constants. (thanks to
+ Max-Gerd Retzlaff)

+ returns T (reported by Anton Kazennikov)
+ * bug fix: the STORE-VALUE restart of CHECK-TYPE works correctly
+ with non-variable places
+ * bug fix: remove a race condition in the setting of
+ funcallable-instance functions, this should make threaded CLOS
+ code more stable against memory faults.
+ * bug fix: corruption of specials when unbinding is interrupted by an
+ asynchronous unwind (reported by Hannu Koivisto)
+ * improvement: the debugger will now also display local variables that
+ are only used once, for code compiled with a DEBUG optimization quality
+ of 2 or higher.
+
+changes in sbcl-0.9.17 (0.9.99?) relative to sbcl-0.9.16:
+ * feature: weak hash tables, see MAKE-HASH-TABLE documentation
+ * incompatible change: External-format support for FFI calls. The
+ SB-ALIEN:C-STRING no longer implies an ASCII
+ external-format. Instead the string is subject to external-format
+ conversion. Additionally return values of type SB-ALIEN:C-STRING
+ are by default of type (SIMPLE-ARRAY CHARACTER), not
+ SIMPLE-BASE-STRING. For an alien type that behaves like the old
+ SB-ALIEN:C-STRING type, use (SB-ALIEN:C-STRING :EXTERNAL-FORMAT
+ :ASCII :ELEMENT-TYPE BASE-CHAR). (thanks to Yaroslav Kavenchuk)
+ * incompatible change: SB-EXT package no longer contains the
+ following unused symbols: *GC-NOTIFY-AFTER*, *GC-NOTIFY-BEFORE*,
+ *GC-NOTIFY-STREAM*, *ERROR-PRINT-LENGTH*, *ERROR-PRINT-LEVEL*,
+ *ERROR-PRINT-LINES*
+ * incompatible change: the single-stepper is no longer available
+ on Alpha, Mips and Sparc platforms.
+ * minor incompatible change: the direct superclasses of
+ SB-MOP:FUNCALLABLE-STANDARD-OBJECT are (FUNCTION STANDARD-OBJECT),
+ not (STANDARD-OBJECT FUNCTION). This makes the
+ class-precedence-lists of GENERIC-FUNCTION and
+ STANDARD-GENERIC-FUNCTION comply with the requirement of ANSI
+ 1.4.4.5.
+ * minor incompatible change: the default stream external format on
+ non-unicode SBCL is no longer detected from the locale, but is always
+ ISO-8859-1
+ * new feature: Add a version of evaluator that uses an interpreter instead
+ of the compiler. EVAL still uses the compiler by default, to switch it
+ to use the interpreter, set the value of the variable
+ SB-EXT:*EVALUATOR-MODE* to :INTERPRET.
+ * minor incompatible change: the single-stepper REPL has been merged
+ with the normal debugger (see the "Stepping" heading of the debugger help
+ for more details). The debugger command STEP will no longer switch
+ to the single-stepper REPL.
+ * bug fix: ENOUGH-NAMESTRING on pathnames with no name and a pattern
+ for a type now works.
+ * bug fix: loading of default sysinit file works. (thanks to Leonid
+ Slobodov)
+ * bug fix: better detection of circularities in the file-compiler.
+ (reported by Marco Monteiro)
+ * bug fix: the CL pathname functions now work with files that have
+ non-ASCII characters in their names (thanks to Yaroslav Kavenchuk)
+ * bug fix: The :PTY argument for RUN-PROGRAM will now work on
+ systems with Unix98 pty semantics.
+ * bug fix: ASDF-INSTALL will now work with bsd tar.
+ * bug fix: ASDF-INSTALL uses GNU tar on Solaris (thanks to Josip
+ Gracin).
+ * bug fix: timers expiring in dead threads no longer cause a
+ type-error (reported by Paul "Nonny Mouse").
+ * bug fix: thanks to more lightweight single-stepper instrumentation,
+ code compiled with (DEBUG 3) will compile and execute significantly faster,
+ and will have more accurate type-inferencing than before
+ * bug fix: SLOT-VALUE optimizations are no longer done on method parameters
+ whose bindings are modified
+ * improvements to the win32 port (thanks to Yaroslav Kavenchuk):
+ ** bug fix: arguments to RUN-PROGRAM are escaped correctly
+ ** replace dummy implementations of CL:MACHINE-INSTANCE and
+ CL:SOFTWARE-VERSION with proper version
+
+changes in sbcl-0.9.16 relative to sbcl-0.9.15:
+ * feature: implemented the READER-METHOD-CLASS and
+ WRITER-METHOD-CLASS portion of the Class Initialization Protocol
+ as specified by AMOP.
+ * incompatible change: variable SB-EXT:*USE-IMPLEMENTATION-TYPES*
+ no longer exists.
+ * optimization: faster LOGCOUNT implementation on x86 and x86-64
+ (thanks to Lutz Euler)
+ * optimization: hashing of general arrays and vectors has been
+ improved. (reported by Any Fingerhut)
+ * enhancement: SB-INTROSPECT is now able to find definitions of
+ profiled functions. (thanks to Troels Henriksen)
+ * enhancement: compiler-macro expansion applies now to FUNCALL forms
+ as well, allowing compiler-macros for SETF-functions to expand.
+ * enhancement: step-instrumentation no longer wraps known
+ single-value functions with multiple-value context, allowing
+ better type inference.
+ * fixed bug #337: use of MAKE-METHOD in method combination now works
+ even in the presence of user-defined method classes. (reported by
+ Bruno Haible and Pascal Costanza)
+ * fixed bug #339(c): if there are applicable methods not part of any
+ long-form method-combination group, call INVALID-METHOD-ERROR.
+ (reported by Bruno Haible)
+ * fixed bug #361: the :FUNCTION initarg in the protocol for
+ initialization of methods can now be used to override
+ internally-produced optimized functions. (reported by Bruno
+ Haible)
+ * bug fix: extensions of MAKE-METHOD-LAMBDA which wrap the
+ system-provided lambda expression no longer cause warnings about
+ unbound #:|pv-table| symbols.
+ * bug fix: improved the handling of type declarations and the
+ detection of violations for keyword arguments with non-constant
+ defaults.
+ * bug fix: potentially erronous calls to PATHNAME and
+ MERGE-PATHNAMES were being flushed in some cases.
+ (reported by Richard Kreuter)
+ * bug fix: compiled calls to TYPEP were mishandling obsolete
+ instances. (reported by James Bielman and Attila Lendvai)
+ * bug fix: format strings with ~> without matching ~< no longer
+ trigger an AVER, but signal an understandable error instead.
+ (reported by Antonio Martinez)
+ * bug fix: specifying an output-file without a pathname-type for
+ COMPILE-FILE or COMPILE-FILE-PATHNAME resulted in using the type
+ of input-file instead of "fasl". (reported by Robert Dodier)
+ * bug fix: compiler-macro lambda-list parsing of FUNCALL forms.
+ (reported by James Y Knight).
+ * bug fix: compiler-macros-function did not consider the environment
+ argument for shadowing by local functions.
+ * bug fix: compiler-macros expansion was inhibited by local INLINE
+ declarations.
+ * bug fix: inline expansions of known functions were subject to
+ step-instrumentation in high debug policies, leading to problems
+ with type-inference.
+ * bug fix: compiler failed to differentiate between different CONS
+ types in some cases.
+ * bug fix: fixed input, output and error redirection in RUN-PROGRAM
+ for win32. (thanks to Mike Thomas and Yaroslav Kavenchuk)
+ * bug fix: #368: incorrect use of expressed vs. upgraded array
+ element type.
+ * bug fix: #306a: more precise unions of array types.
+ * thread-safety improvements:
+ ** CONDITION-WAIT could return early on Linux, if the thread was
+ interrupted and subsequently continued with SIGCONT.
+ ** STABLE-SORT and ADJUST-ARRAY were not reentrant.
+
changes in sbcl-0.9.15 relative to sbcl-0.9.14:
* added support for the ucs-2 external format. (contributed by Ivan
Boldyrev)
* fixed bug: SPECIALIZER metaobjects (including anonymous classes
and EQL-SPECIALIZERs) can be used as specializers to DEFMETHOD.
(reported by Pascal Costanza)
+ * fixed bug: FINALIZE-INHERITANCE is called from
+ REINITIALIZE-INSTANCE on classes when the class has previously
+ been finalized, as required by AMOP.
* minor code generation optimizations:
- * better register allocation in CLOS dispatching functions
- * overflow detection when coercing signed bytes to fixnums on x86-64
- is now implemented with one IMUL instruction instead of three shifts
- * more efficient bit-vector access on x86 and x86-64
- * more efficient access to raw structure slots on x86 and x86-64
+ ** better register allocation in CLOS dispatching functions

+ ** is now implemented with one IMUL instruction instead of three shifts
+ ** more efficient bit-vector access on x86 and x86-64
+ ** more efficient access to raw structure slots on x86 and x86-64
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** ENSURE-DIRECTORIES-EXIST.8: ENSURE-DIRECTORIES-EXIST must
+ return its argument.
changes in sbcl-0.9.14 relative to sbcl-0.9.13:
* feature: thread support on Solaris/x86, and experimental thread support
faster
